Json 为什么我的CloudFormation命令失败了？

我的命令：

"7-set-up-default" : {
        "command" : { "Fn::Join" : ["", [
                                "robocopy /move C:\\inetpub\\wwwroot\\ C:\\inetpub\\wwwroot\\Default\\\n",
                                "powershell \"Import-Module WebAdministration;",
                                             "Set-ItemProperty 'IIS:\\Sites\\Default Web Site' -name physicalpath -value 'C:\\inetpub\\wwwroot\\Default\\'\""
                            ]]},
        "waitAfterCompletion" : "0"
      },

此堆栈跟踪不太有用，因此失败：

  File "cfnbootstrap\construction.pyc", line 513, in run_config

有人能帮忙吗？

因为robocopy不使用标准返回码。它实际上并没有失败，但命令行将其返回代码解释为失败。看这个

您需要做的是包装robocopy并像这样解释返回值

"a-sync" : {
  "command" : {"Fn::Join" : ["",[
  "(robocopy c:\\latest c:\\inetpub\\", {"Ref" : "Name"}, " /MIR) ^& IF %ERRORLEVEL% LEQ 4 exit /B 0"
  ]]},
  "waitAfterCompletion" : "1"
},

这是从一个有效的sript中剪切和粘贴的，因此您需要更改参数-但关键部分是将robocopy命令括在括号中，并在^&IF结尾处填充

实际上，它将所有来自robocopy的成功返回代码转换为操作系统识别的成功代码

"a-sync" : {
  "command" : {"Fn::Join" : ["",[
  "(robocopy c:\\latest c:\\inetpub\\", {"Ref" : "Name"}, " /MIR) ^& IF %ERRORLEVEL% LEQ 4 exit /B 0"
  ]]},
  "waitAfterCompletion" : "1"
},
